[54.02] The Age of the Globular Cluster NGC 6652 from WFPC2 Imaging

Images of the inner halo globular cluster NGC 6652 have been
obtained with WFPC2 on HST. These images have been used to
derive a V,V-I color magnitude diagram (CMD) for this
moderately metal-rich cluster. The CMD clearly delineates
the principal sequences of this cluster, from the upper
giant branch to \sim 4 magnitudes below the main sequence
turn-off. The reddening, metallicity and distance of NGC
6652 are derived from the CMD. Using a new set of
\alpha-element enhanced isochrones, the age of NGC 6652 is
derived using \Delta V(TO - HB), \Delta (V -
I) and isochrone fitting. This age is compared to
ages of other globular clusters in order to further our
understanding of the formation of the inner galactic halo.
